4 Claims.

The present invention has reference to a meth- 0d of securing bushings or sputs, forming a part of metallic'barrels or drums, designed for shipping liquids, in position.

The primary object of the invention 'is to pro-' vide a method by means of which the sput may be positioned and secured, by pressing or rolling the metal ofthe barrel, over' the outer upper sput may be lacquered, so that the container material shipped or drum may be used in shipping edible foods.

With the foregoing and other o bjects in view, which will appear as the description proceeds, the. invention resides in the combination and arrangement of parts and in the details of con- 's'truction hereinafter described and claimed, it

being understood that changes in the precise embodiment" of the invention herein disclosed,

may be made within the scope of what is claimed,

without departing from the spirit of the invention.

Referring to the drawings:

' Figure 1 is a sectional view through the forming machine employed, in pressing a portion of the drum or container outwardly, adjacent to the opening thereof; 1 Figure 2 is a sectional view through the machine employed in rolling or pressing the"en-- largement of the container, over the upper edges of the sput.

Figure 3 is a plan view thereof. Figure 4; is a sectional view through a container 'and sput secured by the pressing. method, em

bodying this invention.

Figure 51s a fragmental sectional view through the sput and container taken at a point through one of the enlargementsof the sput. I

Referring to the drawings in detail, the reference' character 5 designates the body portion or container, which is formedwith an aperture or opening for the reception of the bushing or sput in which the usual plug is positioned.

A machine is now provided which embodies a stationary former 6 and a movable former 7, into which the body portion or container is positioned in such a way that the formers will act on the body portion or container, ata point, adjacent to the aperture or opening thereof; When the machine is operated, the metallic drum or con:

, is formed, and the sput to be pressing operation, thereby providing a surplus .tainer is pressed outwardly as at 8 adjacent to the sput opening, providing an enlargement, and an inwardly extended annular flange 9. By this pressing operation, the sput, opening tainer is dropped into the opening, with the annular shoulder 10 of the sput resting on the shoulder, as clearly shown by the drawings.

- With the sput in this position, the sput and the container or the sput support are now transferred to a machine which embodies a stationary circular clamping member 11', and a movable circular clamping member 12, which. clamping members have inclined surfaces corresponding to the inclined surfaces of the enlargement of the drum or container, the inclined surfaces of the clamps, cooperating'in gripping and holding the metal of the container or support, at points adjacent ,to the opening, as shown by Figure 2 of the drawings. J 20 The stationary clamp 11 is of a length so that aspace is provided between the upper edge thereof, and the inner surface of the enlargement, of the container or support, formed during the 25 of material above the sput, to be engaged by the circular presser foot of the machine in which the container or body portion; and the sput, are now clamped. i

This circular presser foot is indicated by the 3 numeral 13, and when this presser foot is moved downwardly over the;upper edge of the enlargement, formed by the first stepof the method, and pressure is brought to bear thereon, the

presser foot acts to roll'or press that portion of 5 1 the enlargement of the container adjacent to the sput=opening,- over the upper edge of the sput, as shown at 14 in Figures-1 and 5 of the drawings, thereby securely locking the sput within the sput opening. c

Thus it willflbe seen that when a sput is positioned by the method embodied in this inven- 1 tion, the metal of the container or drum in which the sput is positioned,is rolled over the upper edge of the sput, from a point exteriorally of the sput,'eliminating crevices. or grooves on the inner surface of the container, in which material shipped in the container, may collect.

It is further pointed out that when drums the metallic wall thereof.

secured to the con- 5 j Having thus described the invention what is claimed is:

1. The method of securing metallic sputs in metallic drums, consisting in forming an,opening in a drum, bending the metal'of the drum outwardly at the opening, bending the edge of the drum at the opening inwardly and laterally, placing a sput on'the laterally extended portion of the drum, and finally rolling the outwardly bent portion oil-the drum over the outer edge of the sput an int [engagement with the sput.

2. The method of 1 securing metallic bung bushings for metallic drums, consisting in forming an opening in' a drum, bending the drum outwardly at a point adjacent to the opening, bending the outwardly bent portion inwardly and laterally providing an annular shoulder, po-' sitioning a bushing on the annular shoulder so that a portion of the outwardly bent portion of the drum lies in a position above the bushing, and finally rolling that portion of the drum extended above the bushing, into eng ement with the outer surface of thebushing.

3. The method of securing metallic sputs in metallic drums, consisting in forming an-opening in a drum, bending the metal of the drum outwardly and downwardly adjacent to the opening, and forming an inwardly extended annular flange at theopening, placing a sput on the flange and within the opening of the drum, and finally rolling the metal of the drum over the outer edge of the sput.

4. The methodof securing metallic spots in Leon Moons BELL.
